An irate Michigan father worried over what Obamacare would do to his handicapped adult son reports he was threatened after trying to get a direct answer from Rep. John Dingell, D-Mich., and has a warning of his own for those who made the threats.

“I will use every means available to me, lethal force if necessary, to protect [my son] and my wife. My wife is terrified,” Mike Sola told Fox News today.

Meanwhile, Sen. Claire McCaskill, D-Mo., was confronted by some pointed questions at a town hall meeting of her own, including one referencing the ongoing dispute over President Obama’s refusal to allow public access to his original long-form birth certificate, which probably could establish his eligibility to be president.

In an interview with Fox, Sola explained how he took his wheelchair-bound adult son to the front of the room to confront Dingell, 83.

Sola said he demanded information about what Obamacare would provide for his son, and Dingell responded with a statement that there is an amendment to address the needs of the handicapped.

However, Sola said that amendment doesn’t exist.

The controversy erupted just as House Speaker Nancy Pelosi expressed in a commentary that those who object vocally to the health care plan are “un-American.”

“I was trying to speak as an American in a free country with a right of freedom of speech,” Sola said.

Then he said that “thugs” already have located his home and delivered a threat, although he did not detail its contents. He said it had been reported to police.

Sola said he would “take the risk of going to prison” if the threats were repeated.

And he challenged members of Congress to establish a health care program for themselves and their own families before imposing it on the American public, which has expressed in multiple polls significant opposition to it.

According to a report from Associated Press, McCaskill faced “shouts and jeers” even in “friendly territory.”

At Poplar Bluff, Mo., the report said, an audience of 500 applauded the loudest when Obama was called a socialist.

Another audience member asked, “Where’s the birth certificate?” alluding to the dispute over Obama’s still-unreleased eligibility documentation.

AP reported McCaskill was visibly frustrated and at one point said, “You guys are so mean.”

The Obamacare package will be handled by Congress in a month when members return from several weeks of hearing from their constituents.

As WND reported, Pelosi, D-Calif., has accused attendees at health care town hall meetings of being part of an “Astroturf” movement, saying she didn’t believe the angry constituents represented a legitimate grass roots opposition – and the Democratic National Committee called citizens “angry mobs” who are “seeking to destroy Obama.”

Obama’s own 2008 political campaign, merged with the Democratic National Committee in January and now known as Organizing for America, is also calling on Obama supporters to show up at local representatives’ offices to show support for health reform.

“As you’ve probably seen in the news, special interest attack groups are stirring up partisan mobs with lies about health reform, and it’s getting ugly,” a letter from Organizing for America states. “Across the country, members of Congress who support reform are being shouted down, physically assaulted, hung in effigy, and receiving death threats. We can’t let extremists hijack this debate, or confuse Congress about where the people stand.”
